 Notes on lesson on Force | kullabs.com

#### Force

After completion of this lesson, student must be able to:

• Describe the uses and effects of force on objects at rest and motion.
• Define and explain inertia of rest and inertia of motion.
• Explain scalars and vectors.
• Describe acceleration and retardation with example.
• Explain the equations of motion and solve simple mathematical problems.
• Explain Newton's Laws of motion with examples.

#### Force

Force is an external agency which changes or tends to change the state of a body from rest to motion or vice versa. When a number of forces acting on a body do not change its states of rest or uniform motion in a straight line, the force are said to be balanced forces.This note provide us further information about the force.

#### Inertia and Momentum

Inertia is the property of a body due to which it remains or tends to remain in the state of rest are uniform motion in a straight line unless an unbalanced forces act on it. This note provides us the information about inertia of force and different forms of inertia and momentum.

#### Equation of Motion of Uniform Acceleration

Equations involving displacement, initial velocity, final velocity, acceleration and time of motion of a moving body are equations of motion. This note gives us the information about equation of motion of uniform acceleration and its derivation.

#### Newton’s Laws of Motion

Newton’s first law states that ‘everybody continues in its state of rest or of uniform motion in a straight line unless an unbalanced force acts on it.' This notes provides an information about Newton’s laws of motion.
